Astrid Peterman is fighting with regular forces and has already shown herself to be a skilled fighter, driven in her desire to push back the invaders and seek revenge. She proves herself and is taken on by Captain DeSalva to become an assassin. She must further prove herself as a young woman in a male-dominated world. She decides that she will have no red lines, and nothing will be off limits when she is on a mission.
Riedel enters the enemy country as a deep cover spy, easily able to pass himself off as a native, and whose sole mission is to find out what the wonder weapon is.
Brigit Malaya, the enemy officer also has to prove herself, not only by fighting against her enemies, but in fighting against the deep-rooted misogyny in her country that devalues women. She works her way up through the ranks by virtue of brutal combat and is hardened by it; her ambition overriding her humanity, and all the while she is unaware that she is being watched and admired by the country’s dictator.
